--- Comment #5 from David Binderman <dcb314 at hotmail dot com> --- I tried a git bisect and got this: $ git bisect good 6fa4b0135439d64c 30cfdd6ff56972d9d1b9dbdd43a8333c85618775 is the first bad commit commit 30cfdd6ff56972d9d1b9dbdd43a8333c85618775 Author: Robin Dapp <rd...@ventanamicro.com> Date: Fri May 17 12:48:52 2024 +0200 RISC-V: Remove dead perm series code and document. which doesn't look very plausible ;-| I think someone else ought to have a go at a bit bisect and a reduce.
